Ordering Information5.1 It is useful for the purchas

41、er to consider the followingitems when buying rainwear under this specification. Includethese items, as necessary, in purchasing documents:5.1.1 Type of material,5.1.2 Fabric weight, g/m2(oz/yd2),5.1.3 Type and material of fasteners (buttons, snaps,zippers, or hook-and-loop fasteners),5.1.4 Reflecti

43、n of conformance to this specification.6. Materials and Manufacture6.1 The rainwear shall be designed and manufactured usingmaterials and seam constructions that meet the requirementsfor leak resistance in 7.3.6.2 Mechanical fastener closures, such as buttons or snaps,shall be designed and construct

44、ed so that they are covered bythe rainwear outer layer material.6.2.1 This will result in the garment having a multiple layerconstruction in the area of the closure. This will also preventthe closure hardware from being directly exposed to thethermal hazard.NOTE 1In limited testing, it has been foun

45、d some uncovered closuresmelt and fuse. Constructing the closures so that they are covered asdescribed above is designed to mitigate the melting and fusing observedwith uncovered closures.7.

47、and dry in accordance withAATCC Method 135 (3, IV A iii).7.1.2 For limited-use or disposable rainwear with careinstructions indicating the rainwear is not to be cleaned, test therainwear material sample only as received or as manufactured.7.2 Weight and Weight Uniformity Rainwear Material:7.2.1 Dete

48、rmine the average weight in g/m2(oz/yd2)oftherainwear material sample submitted for the material testing in7.3, 7.4, and 7.5 (optional) in accordance with Test MethodsD3776/D3776M, Option B. If a single sample of rainwearmaterial is used for all of the designated tests, one averageweight determinati
